Observational Registry of the Treatment of Glanzmann's Thrombasthenia

United States, Algeria, Austria218 participantsStarted 2004-01

Plain-language summary

This observational registry is conducted in Europe, Asia, Africa and the United States of America (USA). The purpose of the registry is to evaluate the efficacy and safety of activated recombinant human factor VII (rFVIIa) during bleeding episodes and for the prevention of bleeding during invasive procedures/surgery in patients with Glanzmann's thrombasthenia (GT) with past or present refractoriness to platelet transfusions. Attention will be directed towards complications related to thrombo-embolic events and concomitant medications especially antifibrinolytics.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients with congenital GT defined as patients with lifelong bleeding tendency characterised by impaired or absent platelet aggregation, impaired clot retraction and prolonged bleeding time or prolonged platelet function analyser closure time. The patient has normal platelet counts and platelet morphology. Optional diagnosis criteria are quantitative or qualitative evaluation of GP (Glycoprotein) IIb/IIIa receptor including flow cytometry and identification of gene defects * Signed informed consent by the patient or next of kin or legally acceptable representative to collect data on treatment of a given bleeding episode or surgical event as specified in the protocol. If informed consent is provided by the next of kin or legally acceptable representative, consent must also be obtained from the patient as soon as he/she is able to do so. Informed consent must be obtained before entry of data into the registry Exclusion Criteria: * Patients with acquired thrombasthenic states caused by autoimmune disorders (acute or chronic) or drugs

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

For surgery including invasive and dental procedures: Haemoglobin level

Timeframe: prior to surgery and 24 hours after surgery

For surgery including invasive and dental procedures: Overall haemostatic evaluation by the surgeon

Timeframe: 24 hours after surgery
